CHARLES H. SNYDER, OF JACKSON, MICHIGAN, ASSIGNOR TO THE MONITOR WATERPURIFIER COMPANY, OF SAME PLACE.

FEED-WATER PURIFIER.

SPECIFICATION forming part of Letters Patent No. 550,425, dated November26, 1895.

Application filed August 5, `1895. v

son, in the county of Jackson and State of Michigan, have inventedcertain new and useful Improvements in Filters; and I do declare thefollowing to be a full, clear, and eX- act description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to improvements in that class of apparatus forheating and purifying the water fed to boilers in which theexhaust-steam from an engine is utilized as the heating agent and alloil and grease is separated from the steam before it comes in contactwith the water to be heated. v

The novelty and advantages of my invention will be fully understood fromthe following description and claim when taken in connection with theaccompanying drawings, in which- Figure l is an elevation, partly insection, of my improved apparatus complete. Fig. 2 is a vertical sectionof the oil and grease separator. Fig. 3 is an end view of one of theplates of the said separator. Fig. 4 is a detail plan view of the valvefor controlling the feed-water inlet. Fig. 5 is a detail plan View ofthe plate which rests above the filtering material and serves to retainthe same in position, and Fig. 6 is a plan view of the sectionalforaminated plate on which the filtering material rests.v

Referring by letter to said drawings, A indicates the casing of myimproved apparatus. This casin g is formed of any suitable materialcapable of withstanding steam-pressure, and at its lower end is arrangedthe iiltered-water chamber a, which is provided with a water-glass b,designed to indicate the height of the filtered Water, and a drain-pipec, having a cock d, and is designed to be connected by a pipe e with aboiler. Above this chamber a, placed upon suitable supports, is theforaminated diaphragm f, which is designed to support the filteringmaterial g and is made in two sections b, as shown in Fig. 6, so as topermit of it beingreadily removed through the opening normally coveredby the door i when the filter is to be cleaned. The filter- Serial No.558,309. (No model.)

ing material-g, which may be any substance suitable to the purpose, is,as stated, placed on the diaphragm f, and it is retained in position andprevented from rising with the water by the suitably-supported plate ordiaphragmj, which is preferably perforated in the manner better shown inFig. 5, so as to permit free passage of the water to the filteringmaterial.

k indicates a pan which is supported upon lugs p or other suitablesupports Z at about the proportional distance illustrated above theplate j. This pan k is provided with a plurality of openings m,surrounded by walls n, which are almost as high as the side walls p ofthe pan, and it is also provided with a central opening q, surrounded bya wall o, quite as high as the said walls p. By virtue of thisconstruction of pan it will be readily seen that pockets s are formedfor the reception of sediment, and that when water is fed into the panit will pass in a thin film over the Walls n andrand down through theopenings m q, while the sediment and foreign matter in said water willsettle to the bottom of the pockets s.

7.9 indicates a plurality of pans which are placed one above the otherabove the pan lo, and are similar to said pan k, except that they areprovided with legs t. All of these pans 7.: k' are removably placed inposition, and it will therefore be seen that when the cap -plate a ofthe casing is disconnected said pans may be readily removed, so as topermit of them being easily cleansed.

o indicates the feed-water-inlet pipe, which communicates with theinterior of the casing A above the pans 7e k,as shown in Fig. l. Thispipe o is provided with a valve w, which has a stem ai, and to this stemis connected an arm y, which in turn is connected to a lever e,fulcrumed at a', the parts being so arranged that when said lever israised the valve will be closed and the supply of water cut o. Theleverz is connected by a rod b with a float c', arranged in a cylinderCW, and as said cylinder is connected by a pipe or pipes e with thefiltered-water chamber a it will be seen that when the filtered waterrises to a certain height the valve w will be closed through the mediumof the mechanism de* IOO enabled to purify the Water before it is feditothe boiler.

In order to heat and boil the Water, I contemplate utilizing theexhaust-steam from an engine. This steam is ordinarily impregnated withgrease and oil, and in order to free the steam of the same Iprovide theoil and grease separator vhichhasits opposite sides connected by pipes CD With an engine 'and the filter-casing A, respectively, `and 'isTprovided Witha glass E to indicate fthefamount of oilorgreasecollectcdintheseparator, and with a drain-piped?, havingcacockG. `Said separator `ihas the `pipes 'C D fentering `its -op-.positesides, as statedyand betweensaidpipes are arranged theforaminated:platesiI'Ivhieh are designed to permit the steam to ,passifrom pipe Cto pipe D, and yet catch oiwgatherithe oil and grease and permit'thessame to drip intothe bottom ofthe separator. Said plates areremovably placed in `the separatOrTB, so

`that they can be removed and cleaned when' necessary, and `in order`topresenta:gggrea'ter surface `to the steam, so vas to enable them tobetter gather the oil and Lgrease, 'they :are corrugated, as bettershown `in :Figs 2 and 3. `It will also be `perceived that A.by ireasonof :theplates Hbeing corrugated .channels are formed which .guide thecollected oil directly to the bottoni-of the casing :and 4prevent itfrom `spreading over `the .plates and :interfering with the operationthereof.

rlhe pipe Denters `the casing `A above the filtering materiahas showmandit willftherefore be seen that the steam and waterwillbe thoroughlycommingled Ain the `space .above the filtering material and in `the=pans kk',

and inconsequence the water will not only `be heated, which is obviouslydesirable, but will be boiled, whichisalso desirable,=sinee itfacilitates the separation of foreign matter from thev Water.

The exhaust-steam after `passing -:through therwater andcommingling.therewith passes outiof the casing Athrough vthe pipe T, asshown in Fig. l.

When my improved apparatus is employed, it Will be observed that theWater will be fed to theboiler in a purified and heated state, andit'will therefore be seen that it is necessarytol consume but acomparatively small amount of fuel to generate Steam and that noincrustations Will form on the boiler and therefore the boiler Will lastmuch longer and Will be much more efficient than a boiler into which`Water is fed direct from a source of supply.
